  Abstract

Currently, over 90% of Internet traffic uses the TCP (Transmission Control Protocol). In 2016, Google proposed a new congestion control algorithm called BBRv1 (Bottleneck Bandwidth Round-trip Propagation Version 1) to improve network speed. However, BBRv1 had several issues with small buffers, leading Google to propose BBRv2 in 2019. Unfortunately, when flows of BBRv2 and CUBIC share bottleneck bandwidth in a large buffer (2 BDP or more), it causes fairness issues. This paper proposes the F-BBRv2 algorithm to address the fairness issue between BBRv2 and CUBIC.
